I'm currently working on a laptop for someone who at first was having trouble with the laptop not recognising any wireless network connections, but now I have a different issue.
When switching the laptop on, the fan starts up for a few seconds then stops - the screen stays blank and that's it! I've taken the whole thing apart and checked things like the RAM, connection from the motherboard to the screen etc... but it all seems fine. Just before this though I was having issues with the screen flickering and showing horizontal grey lines.
Can anyone shed any light on this please? Thanks in advance!
